Samsung is set to release the results of its Galaxy Note7 investigation on Monday, explaining the underlying causes of the problems that led to the phone’s demise. The three independent quality control and supply chain analysis firms Samsung engaged to conduct the investigation concluded that the Note7 was affected by two separate issues. One was a battery issue; the other was the rush to market. The battery issue reportedly originated with batteries made by Samsung SDI, which did not fit inside the phone properly, leading some devices to overheat, catch fire or even explode.

Three owners of Galaxy Note7 smartphones this week filed a complaint in a federal court in New Jersey that could become a class action lawsuit against Samsung. “Plaintiffs and the Class have suffered injury in fact, incurred millions of dollars in fees, and have otherwise been harmed by Samsung’s conduct,” the complaint states. Samsung recalled the phones and stopped producing them after faulty batteries caused a number of the original products and their replacements to smoke and ignite.

Samsung has stopped production of its problematic Galaxy Note7 smartphones, according to multiple press reports Monday. The company had been offering replacements of the phone after issuing a recall due to defective batteries, but all four major carriers have stopped doing so, presumably because several of the replacements exhibited similar problems, including smoking and catching fire. Two replacements have malfunctioned, according to widely publicized accounts. One began crackling and smoking on board a Southwest Airlines plane.

In an update to its Galaxy Note7 recall, Samsung announced that more than 500,000 new replacement devices would be available for exchange at U.S. retail outlets on Wednesday. The company also announced the rollout of a software update that will display a green battery icon on the screens of new Note7 devices to distinguish them from those subject to recall. “We are delivering as promised and moving quickly to educate consumers about the recall and make new Note7s available,” said Tim Baxter, president of Samsung Electronics America.
